Picture channel and information transfer method thereof

Abstract

The invention discloses a picture channel and an information transfer method thereof. The method includes the steps: establishing a print cache with the breadth as same as that of a note needing to be printed according to information characters inputted by a user; writing part or all of the information characters into service convention positions in the print cache; subjecting the part or all of the information characters to standard two-dimensional matrix barcode coding; converting a standard two-dimensional matrix barcode obtained by coding to a two-dimensional code with the resolution ratio of 120*72dpi; writing the two-dimensional code with the resolution ratio of 120*72dpi into the service convention positions in the print cache; and driving a 9-pin stylus printer to print contents of the print cache on a principal plane of the concatenated note.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to an image channel and an information transmission method thereof. Background technique [0002] When the existing bills transmit information, the transmitted information characters are printed on the paper of the bill by the printer controlled by the computer system. The information characters on the paper include Chinese characters, numbers, letters and other punctuation marks, and these characters can be directly read by people. Reading recognition, when computer system recognition is required, an OCR (Optical Character Recognition, optical character recognition) technology is generally applied. First, the receipt is scanned into a picture file with a scanner and input into the computer system, and the computer system starts to run an OCR software program. The image is recognized and processed, and the OCR software program outputs the information on the bill for use by th...

Problems solved by technology

Conversely, if the area of ​​the entire symbol is limited, then in order to accommodate more information, the size of the module needs to be defined relatively small, but it is too small to be recognized, which is equivalent to two contradictory indicators

[0006] The above-mentioned bills are multi-page, the printer is a dot matrix printer, and a simple one-dimensional or two-dimensional barcode is used. However, it is required to contain hundreds of digits in the limited area. This requirement cannot be solved by the current technology, because the current technology contains hundreds of digits in this use case, which means that the area of ​​the QR code will become very large. Beyond the limited range, when the area is satisfied, the QR code containing so much information becomes unrecognizable again
